AirPods 2 are perhaps the most anticipated gadget in Apple's unpublished product range. The smart in-ear headphones are big sellers for the company and the desire for an updated version seems pretty widespread.

A new report from My Smart Price indicates that a listing has appeared describing AirPods from Apple, with two model numbers (A2031 and A2032) have been going through Bluetooth Special Interest Group certification. For reference, the current AirPods have the model number A1523, A1722 and A1602 marked on the box, indicating left and right AirPods and charging case.

My Smart Price believes they have now passed through this mandatory certification process. The listing indicates an upgrade to Bluetooth 5, which suggests the two new model numbers refer to a left and right earbud rather than the charging case. Bluetooth 5 makes for better range, better data broadcasting and more. It's also important for Internet of Things compatibility. The latest iPhones have Bluetooth 5 compatibility, since the iPhone 8. The new capability also means reduced power usage and better battery life as a result.

It's also striking that the listing names the product as AirPods, which is enough to whet our appetites.

Since the wireless charging case for AirPods, the one that will work with the AirPower charging pad, has been announced some time ago, this listing also strongly suggests that it's upgraded earbuds that are being described here.

To be clear, none of this specifies a release date, but Bluetooth certification is usually a strong hint that it's ready to go on sale.
